The working principle of the vibratory grinding mill is based on intense motion of the grinding balls, with both inertia and centrifugal forces. The energy produced using the Sweco mill is higher than that produced by the ball mill, making it more effective in reducing the particles size to micron or less.

The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process. Furthermore, by ...
